Ghiani G., Leporini B., Paterṇ F. Vibrotactile feedback as an orientation aid for blind users of mobile guides. In: MobileHCI 2008 - MobileHCI 2008. 10th International Conference on Human-Computer Interaction with Mobile Devices and Services (Amsterdam, The Netherlands, 2-5 September 2008). Proceedings, pp. 431 - 434. ACM, 2008.
In this paper, we present a solution for supporting vibrotactile feedback in mobile museum guides for blind users. To this end, we have designed and implemented a hardware/software module, which can be easily plugged into current PDAs to assist blind users in orientation. The solution, which comprises a twochannels haptic module as well as vocal support, has been exploited for moving through tagged objects. We also report on a user evaluation carried out with a number of blind users.
